Questions with Complete Solutions
proliferative phase second phase of the endometrial cycle during which the endometrium
regenerates; this phase is under the control of estrogen and typically lasts from day 6 to day 14 of
the menstrual cycle
secretory phase third phase of the endometrial cycle during which the rebuilt
endometrium becomes edematous to prepare for possible fertilized ovum implantation; this
phase is under the control of progesterone and lasts from day 15 to day 28 of the menstrual cycle
ischemic phase fourth phase of the endometrial cycle in which decreased levels of
estrogen and progesterone causes constriction of the spiral arteries of the endometrium, allowing
the endometrial lining to shed; this phase occurs during days 27 and 28 of the menstrual cycle
hypothalamic pituitary cycle part of the menstrual cycle that involves secretion of
hormones required to stimulate ovulation; the hypothalamus secretes GnRH and the anterior
pituitary gland secretes FSH and LH
,GnRH (gonadotropin-releasing hormone) hormone secreted by the hypothalamus to
stimulate release of FSH and LH from the anterior pituitary gland
FSH (follicle stimulating hormone) hormone produced by the anterior pituitary gland that
stimulates the ovaries to develop follicles (oogenesis) and secrete estrogen; controls the follicular
phase
LH (luteinizing hormone) hormone produced by the anterior pituitary gland that
stimulates ovulation and formation of the corpus luteum, which in turn leads to a rise in
progesterone levels; controls the luteal phase
ovarian follicle a sac-like cluster of epithelial cells surrounding an oocyte
ovum a mature egg cell that can divide to give rise to an embryo after fertilization by a
sperm cell

from the LMP, then add 7 days; change the year if necessary
, gravida (G) total number of times a woman has been pregnant, including a current
pregnancy; includes abortions, miscarriages, and stillbirths
para (P) number of pregnancies that have reached at least 20 weeks and have ended
(whether through stillbirth or a viable birth); current pregnancy is not counted
multifactorial inheritance pattern of inheritance in which a trait is influenced by both
genetic and environmental factors
unifactorial inheritance pattern of inheritance in which a certain trait or disorder is
controlled by one gene; risk for transmission to offspring can be estimated
carrier person who has one recessive allele for a trait or disorder, but does not have the
trait or disorder
inborn errors of metabolism disorders of fat, protein, or carbohydrate metabolism;
recessive pattern of inheritance
